SLEEPER FOR PERMANENT WAY.

" Britain. residing in London, Englainhhave invented certain new and useful improvements in Sleepers for Permanent Way, of which the following is a specification.

It has frequently been proposed to stamp or cut from a metal sleeper tongues which when turned up each from its own individual slot serves to holda rail. \Vhen this is done in such a manner that the tongues are turned up toward each other plenty of metal is available for foi'n'iing the two Jaws of a chair and there is a seating for the rail between the jaws. \Vhen, however, the tongues are turned up away fron'neach other, the metal left as a seating so far reduces that available for holding the rail, that only one chair jaw has been formed, the other tongue serving merely as a ,clip for the fiangeor lower head of the rail; or at best short abutments for specially shaped keys have been formed, which cannot be regarded as constituting an efficient support forthe rail.

The principal object of the present invention is to provide a combined sleeper and chairof exceedingly simple and inexpensive ciinstruction which will conform to the ac cepted and demonstrated standards if the practical art and which can be used for the heaviest and fastest main line tratiic, in such use maintaining a perfectly safe and secure grip of the rail. v

By my invention I turn up both the tongues from one and the same slot, and thus'form from the metal of the sleeper one or more jaws of a chair which is preferably -of the type wherein the rail is held in position by ,a wedge or wedges at one or both sides, leaving no metal between separate slots to act as a seating for the rail, which is instead supported by the parts of the sleeper, made suitable for the purpose, on each side of the slot.

The relative lengths of the tongues made made about the middle of the slot and at right anglesto the edge of the sleeper, the

tongues are of sutlicient length to, serve as v Specification of Letters Patent.

aws of a chair for supporting a rail of cor tain rail sections. being long enough for; this purpose, whether one jaw be bent to abut directly against the web of the rail, the other ]il\\' holding a key, or whether both aws are provided with keys. If thecut is made at unequaldistances from the ends of the slot, one tongue may constitute a aw Patented Aug. 8, 1916. Application filed May 17, 1915. Serial No. 28.80 6.

and the other merely a clip for the flange or lower head of the rail.

In making the aws of a chair for some rail sections, however, a simple transverse cut at right angles to the edge of the sleeper does not provide tongues of -suliicient length for forming the two jaws. In this case, therefore, I cut the metal transversely along a line inclined to the edge of the sleeper or along a curved or stepped or otherwise irregular line. In this manner each tongue is longer or of greater effective. length at one part and shorter at the-other paitsthan it would have been had the cut been atright angles to the edge ojf the;

For example the transver' I cut sleeper. may be such as to leave one tongue vith a single tooth at the middle part of its width and the other with two teeth, one at each side. An exaggeration of this leads nactica-lly to two tongues forming one o the jaws and a single tongue forming the other. .\Vh'en strengthening metal for the jaws is desirable this may be in therfoi'ni of a rib or ribs preferably on the upper face of the sleeper or tongue, although other ribs for strengthening the sleeper may be on the i under face. corrugations are an obvious equivalent of ribs. When the strengthening metal is a thickened portion of the metal" substantially (Po-extensive in width with the tongues, it may be on the upper or under face of the sleeper or tongue or on both.

The accompanying drawings illustrate" several forms of the invention.

F'gure 1 is an elevation of one end of a sleeper showing achair formed of tongues of the metal according to the invention. Fig. 2 is a plan of same. Fig. 3 is aside elevation and Fig. 4 a top plan view of: one.

end of a sleeper showing a modified ar-- rangeinent. of Figs. 3 and at. Fig. (3 is'an elevation showing another inmlification. Fig. 'I is plan of same. 8-8 of Figs. 6 and 7. Fig. J is a similar Fig. 5 isaseetion on line 55"" '105 Fig. 8 shows afsect-ion on line Figs.- 8 and 9 and respectively showing a further modification. In the simplest form of the invention shown in F igs. 1 and 2,'the plate orblank forming the 'bodyof the sleeper is of unlform section throughout and at the place where the chairs or rail jaws are to be formed a longitudinal slot C is cut or stamped in the metal and the strip of metal filling the slot is transversely severed in the center, the two tongues B thus formed being turned upward and away from one another to form the jaws of the chair to receive the 'rail. As shown in these two figures the chair is constructed'to receive a flanged rail D, which is held in position between the jaws, which are preferably somewhat inclined to one another, by a distance piece E and a wedge or key F. The distance piece j is preferably. grooved or formed with shoulderse to embrace the sides of the jaw B to preventits movement longitudinally of the rail. The end portion of the sleeper may bebent slightly upward to give the necessary cant to the rail. The sleeper is preferably---1na-de of such Width that the parts a at the sideof the slot B are of sufficient strength to bear the rail without any special reinforcement.

The construction shown in Figs. 3 to 5 is similar to that above described except that the sleeper A is" strengthened by'a longitudinal rib a on its upper face WlllCll is so arranged that it coincides with the tongues B and, when these are cut and bent upward, serves to reniforce them. Strengthening ribs a may also if desired be formed on the underside of the sleeper A.

In the arrangement illustrated in Figs. 6 and 9 the invention is shown 'asappIied to the formation of a chair in which the jaws are required to be longer than can be obtained by a simple transverse cut of the strip forming the jaws, as for instance, when a bull head rail is used, and one of the jaws is required to abut directly against the web of the rail. To obtain such increased length of the jaws B the strip of metal forming thea aws is cut or severed along a stepped or irregular line so that the jaws B are of the shapes shown in Figs. 8 and S). In this case gether the depth of the stepping in such transverse cut may be increased somewhat in the manner indicated in Figs. 11 and 12.

Another method of cutting the tongues to obtaingreater length is shown in Fig. 10.

In this case the tongues B are formed by a straight out made at an inclination across the strip, cut out from the slot C in the,

the best means I know of carrying the same into practical efi'ect, I claim 1. A metal sleeper having jaws formed integral with the metal of the sleeper and turned up from a single slot to provide the jaws of a chair in which the track rail is retained by the coiiperation of both of said jaws with the web of the rail and by the cooperation with one of said jaws of a Avedge interposed between it and said web, said sleeper having seatings for the rail integral therewith at opposite sides of said slot.

2. A metal sleeper having track-rail-receiving jaws formed integral with the metal of the sleeper and turned upward and away from one another from a. single slot to provide the jaws of a chair in which the track rail is retained by the cooperation of both of said jaws with the web of the rail and by the upper portion thereof and severed approximately at its center to form jaws of substantially equal length, said jaws being turned up from the single slot formed by cutting the strip and providing a chair in which a track rail is held by the coiipcration of both of said jaws with the web of the rail and by the cooperation with one of said jaws of a wedge interposed between it and said web, said sleeper having seatings for the rail integral therewith at opposite sides of said slot.

4. A metal sleeper having a strip cut therefrom and struck upwardly and leaving a single slot, the strip being transversely severed to provide jaws of approximately equal length but longer than half the length of the slot from which they are formed, the jaws serving as a chair to receive a track rail and a being each formed to cooperate with the web of the rail. 5. A. metal sleeper having jaws formed integ ally with the metal of the sleeper and turned up from a single slot to form a chair to receive the track rails in which the metal strip cut from the sleeper to form the jaws is severed irregularly so as to form jaws both of which coiiperate with the web of the rail and the sum of whose over all lengths is greater than that of the slot from which they are cut. 6. A metal slcc er-having jaws formed in tegrally with the metal of the sleeper and turned up from a single slot to form a chair to receive the track rail in which the sleeper is formed with a longitudinal rib upon its uptper face adapted to coincide with and rein orce said jaws.

7 A metal leeper having jaws formed in I d5 tegral with the metal ofthe sleeper-and turned up from a single slot-to form a chair side he slot from which said jaws are formed. 8. A metal sleeper having jaws formed'integral with 'the metal of the sleeper and I turned up from a single slot to provide the jaws-0f a chair in which the track-rail is reita'ined by the cooperation" of both of sald jaws with the web of the rail, said sleeper having seatings for the rail integral therelwith at opposlte sides of said slot.
